To all whom t my concern.'

Be it known that I, PETER Fanmail, subject of the Kingjof Great Britain, residing at Brisbane, Queensland, Australia, have ine vented certain new and usefulV Improvements in Means for Protectin the Springs of Motor Cars and Other Vehicles, of which the following is a specification.

rlhis invention has for its object the production of a' cover or envelope for the springs of motor cars and other vehicles, so that such sprin can always be bathed in oil or other lubricant, and thus have its life prolonged. 'Ihe use of the invention also U prevents dust getting to the spring.

lin carrying out my invention I provide a suitable casing for the centre and ends of the springs the springs between such casings being enveloped in aA flexible covering.

E@ In order that my invention may be better understood, Iwill now describe it with the aid of the accompanying drawings, in Which- Fig. 1 is a sectional view showing a casing for securing the spring and covering.

Fig. 2 is a plan ofsame (cover removed Fig. 3 is a sectional view showing an ternative method of securing the casing and spring. Y

,te Figs. 4, 5, 6, 7, and 8 show lalternative forms of covering.

The casing consistsof the bod A, through whichthespring B passes, an a cover C. The bod VA'ligand sprin B are secured to the axle D y the bolts BI and clips F an oil tight joint being made where the. bolts E pass through the body A (scey Figs. 1 and 2), such as by screwing the bolts through the casin A, or providing suitable washers.

40 0r, t e body A and spring B may be secured to the axle D by U bolts G and nuts, the legs of which pass through bosses or sleeves H on the inside of the body A, the upper part of the legs being coned so that an oil tight joint may be made, The bosses or sleeves H are not quite as high as the spring B. p

'llhe cover C is secured to the body A by studs and nuts J or screws.

Thebody A of the centrecasing and the end casin K has flanges L, to which the ends of t e envelope M, which covers the spring B, are secured, as by. clamps, brazing, screwing, orotherwise. Suitable cushionin may be provided between the end casing and the spring B to prevent rattling. The

- such cushioning may be in the form of spiral or other. springs, felt, leather, or other buffers.

The envelope M may be of round, oval, or other transverse section. It may be of an suitable flexible material without or wit longitudinal joint, according to the material, as woven tubing, corrugated metal tubing (the corrugations being arranged lengthwise), oil proof rubber, leather (whether -ordinary tanned, mineralized, or otherwise treated), canvas, vulcanite, bakelite, or other'like material, either separatelyv or in combination of eithertwo or more of the substances. TheV tubing ma be reinforced with spiral wire on the inside, on the outside, or embedded in the material, or on both the inside and outside. Woven vwire tubing is shown in Fig. 4; reinforced tubing of canvas or other material is shown in Fig. 5; and corrugated metal is shown in Fig. 6. In Fig. 5 the end of the envelo e M is secured to the spring B by a clip Figs. 7 and 8 showy an alternative arrangement wherein the centre casing A C, is dispensed with, the envelope M being corrugated circumferentially in the centre, so that -it may be compressed when the spring B is secured to the axle D. 0r a short tube may -be used in the same manner, having giecenvelope M secured to it, as in the casing It is to be understood that the cover M is made in the form of an oil tight sleeve, which may be slipped over the end of the spring'B. When of leather or other like material, the' edges would be sewn or otherwise secured to ether.

The detalls o carrying my invention into effect may be varied as found desirable, according to the design of the vehicle to which it is applied.

Having now particularly ldescribed and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is A protectin casing for the springs of motor cars an other vehicles including in combination with a stationary part of the car and a leaf spring traversing said car of an open ended metallic section disposed on the stationary part of the vehicle for receiving the spring, integral sleeves formed within and on opposite sides of the casing and provided at the upper ends with seats, U- bolts having their medial portions engaging the up er part of the spring 'and having their enks opposed to the upper sleeve portions and provided with conical ortions enga ing the seats to provide oil tinr t 'oirits there tween, .means for adjustaby o amping the bolts and maintaining the sprino' and the casing in position, a cover removeby arranged on the casing, other metallic sections enveloping the ends of the spring end ie'x- MABEL C.
